アレン・ブラッドリー 1747-L20D

The Allen Bradley 1747-L20D is a highly practical fixed controller in the Rockwell Automation SLC 500 series. Its most notable feature is that it comes with a built-in DeviceNet network interface, which enables it to independently perform control tasks and also easily integrate into modern equipment networks, directly connecting to various intelligent devices. For projects that require reliable control while also aiming to reduce on-site wiring, it is a cost-effective choice. If you have a buy requirement, as a professional supplier, we can provide you with high-quality original brand new products to ensure the stable operation of the equipment.

Product structure

To put it simply, the Allen Bradley 1747-L20D is a "little genius". It has a CPU inside, which acts as the brain, responsible for thinking; it also comes with several input and output ports, which function like hands and feet, allowing it to directly connect to switches and sensors to perform small tasks. The most amazing thing is that in addition to having a regular programming port, it also comes with a DeviceNet network port. This is really impressive as it enables it to be directly plugged into the device network and "chat" with a bunch of other devices, saving a lot of wiring troubles. Finally, it has a row of small lights on its face. Whether it is happy, sick, or busy, you can tell just by looking at the lights. It is extremely convenient for debugging.

Key features

When it comes to its advantages, they are simply too obvious. The most remarkable feature is its built-in DeviceNet communication function, which enables it to directly "chat" with various on-site devices, eliminating a lot of wiring hassles. At the same time, it has a quick thinking process and strong logical processing capabilities, and can run even the most complex programs smoothly. If the built-in interface is insufficient? No problem, it can also be expanded with modules like building blocks. Moreover, the software it comes with is very convenient for programming, and it has an "inspection" function, allowing you to quickly identify any issues and making development and maintenance hassle-free.

Environmental adaptability

The Allen Bradley 1747-L20D is particularly "robust" in terms of environmental adaptability. It was specifically designed for complex environments like factories. Whether it's cold or hot, it can work normally. When those high-power devices are turned on nearby, the power grid is full of interference, but it is basically unaffected. Moreover, it is also sturdy and doesn't mind vibrations or bumps. It can be directly installed on machines. It can also withstand dust and a certain degree of humidity, and can work stably for a long time, which is very reliable.

Compatibility and Integration

In terms of "fitting in", the Allen Bradley 1747-L20D is definitely an expert. It can perfectly match all the siblings of the SLC 500 series, whether it's replacing old ones or adding to an existing system, it is very convenient. Through that DeviceNet interface, it can also seamlessly connect with other (third-party) devices. Connecting to a computer monitor or touch screen is a piece of cake, and data can be exchanged, making it convenient for unified management. The entire software environment is very mature and runs very smoothly.
